I think you might be missing something. I thought it was one of the best, and most moving, episodes of the series.
It touched on many different things: who was Trip, as a person? How is Sim different or less valuable? Are we not just a sum of our memories and experiences? Would we, in the not-so-distant future, see cloned people as less than human?
Connor's performance was wonderful; I actually teared up the first time I watched it.
Of course, the science was silly. But it usually is. It was the STORY that affected me.
But, hey...to each his or her own.
